DID HITLER MISPLACE HIS COMMANDER? He is residing at MAHEC Dental implementing and teaching obnoxious patient care daily under the nameof Dr. Coryell. Dare a patient (unlike a cowarded resident) ask a question and be prepared for the tongue-lashing of your life. Extremely verbally abusive to patients and non-caring. I was so embarrassed I had to rush to my car to escape the harsh treatment and words from Mahec Dental.
